Negative impacts include: interference with shipping and navigation of other sea users, loss of access to fishing grounds, water and sediment contamination, discharges of commissioning fluids, noise, impacts to marine and coastal habitats and species, economic displacement, soil erosion, waste generation, destruction of fauna and flora habitats, release of gaseous emissions, and traffic. Mitigation measures include: (1) providing advanced notice to marine authorities; (2) monitoring safety zone for the safety of the facility and fishermen; (3) using solid control equipment to achieve 5 to 10 percent oil on cuttings; (4) selecting and using completion fluids taking into account its concentration, toxicity, bioavailability, and bioaccumulation potential; (5) preventing excessive speeds and rapid change of direction for vessels when operating in the field to reduce risks of collisions; and (6) designing, operating, and maintaining marine vessels in accordance with international standards such that the risk of accidental spills is minimized.
